Lightning inductionincluding electrostatic induction and electromagnetic induction. Electrostatic induction lightning is usually only dangerous for structures containing flammable and explosive substances such as gasoline, oil, and gas due to the impact of secondary discharge, while electromagnetic induction lightning is only dangerous for modern equipment using electronic components sensitive to electrical impulses in postal, telecommunications, and radio and television structures.
